 * \brief routines to create gr_fir_XXX's
 *
 * This class handles selecting the fastest version of the finite
 * implulse response filter available for your platform.  This
 * interface should be used by the rest of the system for creating
 * gr_fir_XXX's.
 *
 * The trailing suffix has the form _IOT where I codes the input type,
 * O codes the output type, and T codes the tap type.
 * I,O,T are elements of the set 's' (short), 'f' (float), 'c' (gr_complex), 
 * 'i' (short)
